Ok I think I found out why this fell through cracks, MAINTAINERS isn't updated that host1x&tegra is maintained in drm-misc. John, since Thierry is out, can you pls create the MAINTAINERS patch to - point at drm-misc git repo everywhere needed - add any missing host1x paths to the drm-misc entry so that get_maintainers.pl adds the right people for this patch (currently it doesn't) Also should we have at least a 2nd person for tegra stuff (or well maybe nvidia stuff in general) for drm-misc? Currently it's just Thierry, and I don't think that's enough.

Whomever gets volunteered > please follow > > https://drm.pages.freedesktop.org/maintainer-tools/commit-access.html#drm-misc We never actually moved host1x and Tegra DRM to drm-misc completely. There's still a separate tree that feeds into linux-next. This made sense a while ago because there was a lot going on, but development speed has decreased recently, so we may want to fix that. The big benefit is that drm-misc is better oiled than drm-tegra, so getting things merged would be easier for everyone. I'm all in favor of adding a second Tegra person to take pick up the slack when necessary. Thierry

Hm I thought you had a split where you feed -fixes through misc and features through tegra.git? Just listing both trees would cover that. > I'm all in favor of adding a second Tegra person to take pick up the > slack when necessary. Imo features still through tegra.git with just you is fine, there's not going to be anyone else (like ci farms) blocked if that's held up for a bit. It's more the bugfixes where a 2nd nvidia person would be great. -Daniel
